Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a composite slab pin-type lateral connection structure, method, and floor slab. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Traditional lateral connection of composite slabs requires straightening the protruding reinforcing bars on the side of the composite slab, then binding or welding the corresponding reinforcing bars of the two composite slabs, and finally pouring concrete between the two composite slabs to achieve the lateral connection. During the construction process of lateral connection of two composite slabs, construction workers need to straighten the reinforcing bars and bind or weld the corresponding reinforcing bars, which greatly increases the construction time, reduces the construction efficiency, increases the labor intensity of construction workers, and requires high skill levels from construction workers. The quality control of the lateral connection is also poor. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a composite slab pin-type lateral connection structure, method and floor slab, which is convenient and quick to construct, improves construction efficiency, reduces the skill requirements of construction personnel and improves the controllability of connection quality.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide a composite plate pin-type lateral connection structure, comprising two composite plates. The edges of the upper surfaces of the two composite plates for lateral connection are provided with a plurality of first grooves, which correspond one-to-one. The edges of the lower surfaces of the two composite plates for lateral connection are provided with a plurality of second grooves, which also correspond one-to-one. Concrete is poured into the space formed by the corresponding first grooves of the two composite plates, and a first socket mechanism is embedded within the concrete, engaging a first pin. Concrete is also poured into the space formed by the corresponding second grooves of the two composite plates, and a second socket mechanism is embedded within the concrete, engaging a second pin.

[0006] Optionally, in the laminated plate, the first groove and the second groove are staggered along a direction perpendicular to the laminated plate.

[0007] Optionally, the first socket mechanism includes a first socket fixed in a first groove of a composite plate and a second socket fixed in a first groove of another composite plate. The first socket and the second socket include socket bodies. The socket bodies are provided with a first channel that matches the first pin. The socket bodies are provided with a first one-way mechanism so that the first pin can only pass through the first channel in a set direction through the first socket mechanism. One end of the first pin is provided with a plug and the other end is provided with a bent portion. The bent portion cooperates with the first socket mechanism to limit the movement stroke of the first pin in a first direction.

[0008] Optionally, the first one-way mechanism includes baffles located on both sides of the first channel. The outer end of the baffle extends out of the socket body through an opening provided on the side of the socket body and is rotatably connected to a rotating connecting seat provided on the outer side of the socket body. The baffle is located on the side of the opening near the insertion end of the first channel so that when the baffle is rotated to be perpendicular to the axis of the first channel, it can fit against the side of the opening near the insertion end of the first channel. Correspondingly, the two sides of the first pin are provided with slots that match the baffle.

[0009] Optionally, along the insertion direction of the first pin, the slot surface of the downstream section of the slot is perpendicular to the axis of the first pin, and the slot surface of the upstream section forms a set acute angle with the axis of the first pin.

[0010] Optionally, the second socket mechanism includes a third socket fixed in a second groove of a composite plate and a fourth socket fixed in a second groove of another composite plate. The third socket and the fourth socket include a socket body. The socket body is provided with a second channel that matches the second pin. The socket body is provided with a second one-way mechanism so that the second pin can only pass through the second channel in a set direction through the second socket mechanism. One end of the second pin is provided with a plug and the other end is provided with a bent portion. The bent portion cooperates with the second socket mechanism to limit the travel of the first pin in the second direction.

[0011] Optionally, the second one-way mechanism includes baffles located on both sides of the second channel. The outer end of the baffle extends out of the socket body through an opening on the side of the socket body and is rotatably connected to a rotating connecting seat on the outer side of the socket body. The baffle is located on the side of the opening near the insertion end of the second channel so that when the baffle is rotated to be perpendicular to the axis of the second channel, it can fit against the side of the opening near the insertion end of the second channel. Correspondingly, the two sides of the second pin are provided with slots that match the baffle.

[0012] Optionally, along the insertion direction of the second pin, the slot surface of the downstream part of the slot is perpendicular to the axis of the second pin, and the slot surface of the upstream part of the slot forms a set acute angle with the axis of the second pin.

[0013] Secondly, embodiments of the present invention provide a construction method for the composite plate pin-type lateral connection structure described in the first aspect, comprising the following steps: The two laminated slabs are hoisted so that their sides, which are used for lateral connection, are fitted together; A first pin is inserted into a first socket mechanism within the space formed by the first grooves corresponding to the two overlapping plates, and a second pin is inserted into a second socket mechanism within the space formed by the second grooves corresponding to the two overlapping plates. Concrete is poured into the space formed by the first and second grooves, so that the first socket mechanism and the first pin are embedded in the concrete, and the second socket mechanism and the second pin are embedded in the concrete, thus completing the lateral connection of the two composite plates.

[0014] Thirdly, embodiments of the present invention provide a floor slab provided with the composite plate pin-type lateral connection structure described in the first aspect.

[0015] The beneficial effects of this invention are as follows: The present invention relates to a lateral connection structure, method, and floor slab for composite slabs using a pin-type mechanism. When two composite slabs are laterally connected, a first pin is inserted into a first socket mechanism, and a second pin is inserted into a second socket mechanism. The lateral connection between the two composite slabs is achieved through the cooperation between the first pin and the first socket mechanism, and the second pin and the second socket mechanism. Simultaneously, the first socket mechanism is positioned within the space formed by the first groove, and the second socket mechanism is positioned within the space formed by the second groove. After the lateral connection is achieved using the first pin, the first socket mechanism, and the second pin and the second socket mechanism, concrete can be poured into the first and second grooves to embed the first pin, the first socket mechanism, the second pin, and the second socket mechanism into the concrete. This ensures that the surface of the assembled two composite slabs is flat and aesthetically pleasing. The two composite slabs are laterally connected using the cooperation of the socket mechanism and the pin. During construction, workers only need to insert the pin into the socket mechanism; there is no need for straightening and tying of reinforcing bars, greatly reducing construction time, improving construction efficiency, and lowering the skill requirements for construction workers. The quality of the lateral connection is also highly controllable. Attached Figure Description

Detailed Implementation

[0018] Example 1 This embodiment provides a composite plate pin-type lateral connection structure, such as... Figures 1-2 As shown, it includes two laminated plates, namely a first laminated plate 1 and a second laminated plate 2, and the sides of the first laminated plate 1 and the second laminated plate 2 used for lateral connection are attached to each other.

[0019] On the upper surfaces of the first composite plate 1 and the second composite plate 2, a plurality of first grooves 3 are provided at the edges used for lateral connection, and the plurality of first grooves 3 are equally spaced along the length direction of the first composite plate 1 and the second composite plate 2.

[0020] The first grooves 3 of the first composite plate 1 and the second composite plate 2 correspond one-to-one. After the first composite plate 1 and the second composite plate 2 are attached together, the corresponding first grooves 3 form a first space.

[0021] In the lower surface of the first composite plate 1 and the second composite plate 2, a plurality of second grooves 4 are provided at the edge for lateral connection, and the plurality of second grooves 4 are equally spaced along the length direction of the first composite plate 1 and the second composite plate 2.

[0022] The first composite plate 1 and the second composite plate 2 have a plurality of second grooves 4 that correspond one-to-one. After the first composite plate 1 and the second composite plate 2 are attached together, the corresponding second grooves 4 form a second space.

[0023] Both the first space and the second space are filled with concrete. The outer surface of the concrete is flush with the corresponding surface of the first composite slab 1 and the second composite slab 2 to ensure that the overall slab surface is flush and aesthetically pleasing after the first composite slab 1 and the second composite slab 2 are laterally connected.

[0024] Furthermore, in the first laminated plate 1, the first groove 3 and the second groove 4 are staggered along the direction perpendicular to the first laminated plate 1, that is, the first groove 3 and the second groove 4 are alternately arranged along the direction parallel to the first laminated plate 1.

[0025] Correspondingly, along the direction perpendicular to the second composite plate 2, the first groove 3 and the second groove 4 are staggered, that is, along the direction parallel to the second composite plate 2, the first groove 3 and the second groove 4 are alternately arranged.

[0026] A first socket mechanism 5 is provided in the first space, and a first pin 6 is inserted and fixed in the first socket mechanism 5. The first socket mechanism 5 and the first pin 6 are embedded in the concrete of the first space.

[0027] A second socket mechanism 7 is provided in the second space. The second socket mechanism 7 is plugged into and fixed with a second pin 8. The second socket mechanism 7 and the second pin 8 are embedded in the concrete of the second space.

[0028] The lateral connection between the first socket mechanism 5 and the first pin 6, and the second socket mechanism 7 and the second pin 8, are achieved through the cooperation of the first composite plate 1 and the second composite plate 2.

[0029] The first socket mechanism 5 and the second socket mechanism 7 have the same structure, the first pin 6 and the second pin 8 have the same structure, the first pin 6 is inserted into the adjacent first socket mechanism 5 in opposite directions, and the second pin 8 of the adjacent second socket mechanism 7 is inserted into the opposite directions.

[0030] like Figures 3-5 As shown, the first socket mechanism 5 includes a first socket 501 and a second socket 502. The first socket 501 is fixed to the bottom groove surface of the first groove 3 of the first composite plate 1, and the second socket 502 is fixed to the bottom groove surface of the first groove 3 of the second composite plate 2. After the first composite plate 1 and the second composite plate 2 are attached, the first socket 501 and the second socket 502 together constitute the first socket mechanism 5.

[0031] The first socket 501 and the second socket 502 have the same structure, both including a socket body. The socket body adopts a U-shaped structure, including a first part parallel to the bottom groove surface of the first groove 3 and a second part perpendicularly arranged on both sides of the first part. The end of the second part cooperates with the bottom groove surface of the first groove, and a first channel for the first pin 6 to pass through is formed between the two second parts.

[0032] In this embodiment, in the socket body and the first channel, the end of the first pin 6 facing the first pin 6 when it is inserted is defined as the insertion end of the first pin 6, and the other end of the first pin 6 that protrudes is defined as the protruding end of the first pin 6.

[0033] The first channel is provided with a first one-way mechanism on both sides. The first one-way mechanism allows the first pin 6 to move linearly from the insertion end to the extension end of the first channel in a set direction, but does not allow the first pin 6 to move in the opposite direction. The set direction is the direction from the insertion end to the extension end.

[0034] The first one-way mechanism includes baffle 503, specifically: In the socket body, the two second parts are provided with multiple openings 504, which are arranged along the length direction of the socket body. Preferably, the two second parts have two openings 504, and the openings of the two second parts correspond one to one.

[0035] A rotating connecting seat 505 is fixed to the outer side of the socket body above the edge of the insertion end of the opening. The rotating connecting seat 505 is rotatably connected to one end of the baffle 503 via a rotating shaft. The other end of the baffle 503 extends into the first channel. The baffle 503 is located on the side of the opening 504 near the insertion end. When the baffle 503 rotates to be perpendicular to the axis of the first channel, the baffle 503 contacts the side of the opening 504, so that the baffle 503 can no longer rotate toward the insertion end and can only rotate toward the protruding end. The opening 504 forms a space for accommodating the rotation of the baffle 503.

[0036] The outer end of the baffle 503 is rotatably connected to the rotating connecting seat 505 via a shaft, the inner end of the baffle 503 extends into the first channel, and the edge of the inner end of the baffle 503 facing the first pin 6 is chamfered.

[0037] Correspondingly, the first pin 6 has multiple slots on both sides that match the inner end of the baffle. Since both the first socket 501 and the second socket 502 have two baffles 503 on both sides of the first channel, there are four baffles 503 on both sides of the first channel. Therefore, the first pin 6 has four slots on both sides. Specifically: like Figure 6 As shown, the first pin 6 includes a pin body 601. One end of the pin body 601 is provided with a tapered plug 602, and the other end is provided with a bent portion 603. The bent portion 603 extends in a direction away from the bottom groove surface of the first groove 3. Four slots are provided on both sides of the pin body 601.

[0038] The slot is formed by a first locking tooth 604 and a second locking tooth 605. Along the movement direction of the first pin 6, the first locking tooth 604 is located downstream of the second locking tooth 605. The first locking tooth 604 is a right-angled triangular tooth. One of its right-angled sides is fixed to the pin body 601, and the other right-angled side is located away from the plug 602. This side forms one side of the slot surface, which is perpendicular to the axis of the first pin 6.

[0039] The second locking tooth 605 adopts a straight triangular locking tooth. One of its right-angled sides is fixed to the pin body 601, and the other right-angled side is located away from the plug 602. The surface where its hypotenuse is located forms the groove surface on the other side of the slot. The groove surface on this side is distributed at a set acute angle with the axis of the first pin 6, and along the radial direction of the first pin 6, the groove surface is inclined in the direction away from the plug 602.

[0040] During the process of the first pin 6 being inserted into the first socket mechanism in the set direction, the first pin 6 moves from the insertion end to the extension end of the first channel. The baffle first contacts the surface where the inclined sides of the first locking tooth 604 and the second locking tooth 605 are located. As the first pin 6 moves, it drives the baffle 503 to rotate towards the extension end. When the plug 602 extends to the outside of the first socket mechanism 5 and the bent part 603 contacts the first socket mechanism 5, the inner end of the baffle 503 is engaged in the corresponding slot. Since the baffle 503 contacts the slot surface perpendicular to the axis of the first pin 6, the movement of the first pin 6 in the opposite direction to the set direction is restricted by the cooperation of the baffle 503 and the slot. The movement stroke of the first pin 6 in the set direction is restricted by the cooperation of the bent part 603 and the first socket mechanism 5, thereby making the first pin 6 and the first socket mechanism 5 plugged and fixed.

[0041] The first pin 6 connects the first socket 501 of the first composite plate 1 and the second socket 502 of the second composite plate 2, thus realizing the lateral connection between the first composite plate 1 and the second composite plate 2.

[0042] Furthermore, the bottom end of the second part of the socket body is fixed on the mounting plate 506, and the two sides of the mounting plate 506 are fixedly connected to the bottom groove surface of the first groove 3 by bolts.

[0043] In this embodiment, the adjacent first socket mechanisms 5 are installed in opposite directions.

[0044] The structure of the second socket mechanism 7 is the same as that of the first socket mechanism 5, specifically: like Figure 7 As shown, the second socket mechanism 7 includes a third socket fixed in the second groove 4 of the first composite plate 1 and a fourth socket fixed in the second groove 4 of the second composite plate 2.

[0045] The third and fourth sockets include a socket body, which adopts a U-shaped structure. Its open side is fixedly connected to the bottom groove surface of the second groove. The U-shaped structure forms a second channel that matches the second pin 8. The socket body is provided with a second one-way mechanism. In this embodiment, the second one-way mechanism is provided on both sides of the second channel so that the second pin 8 can only pass through the second channel in a set direction through the second socket mechanism 7. One end of the second pin 8 is provided with a plug, and the other end is provided with a bent part. The bent part cooperates with the second socket mechanism 7 to limit the movement stroke of the second pin 8 in the set direction.

[0046] The orientation is set from the insertion end to the extension end of the socket body and the second channel. The definition of the insertion end and extension end of the socket body and the second channel is the same as that of the insertion end and extension end of the first socket mechanism.

[0047] The second one-way mechanism includes baffles located on both sides of the second channel. The outer end of the baffle extends out of the socket body through an opening on the side of the socket body and is rotatably connected to a rotating connecting seat on the outer side of the socket body. The baffle is located on the side of the opening near the insertion end of the second channel so that when the baffle is rotated to be perpendicular to the axis of the second channel, it can fit against the side of the opening near the insertion end of the second channel. Correspondingly, the two sides of the second pin are provided with slots that match the baffle.

[0048] The second one-way mechanism is configured in exactly the same way as the first one-way mechanism 5, and its further technical details will not be repeated here.

[0049] Along the insertion direction of the second pin 8, the slot surface of the downstream part is perpendicular to the axis of the second pin, and the slot surface of the downstream part forms a set acute angle with the axis of the second pin.

[0050] In this embodiment, the slot of the second pin 8 is formed in the same way as the slot of the first pin 6, and will not be described again here.

[0051] The second pin 8 can pass through the second channel in the second direction until the plug of the second pin 8 extends to the outside of the second socket mechanism 7. The bent part contacts the second socket mechanism 7. Through the cooperation of the baffle and the slot, the movement of the second pin 8 in the first direction is restricted. Through the cooperation of the bent part and the second socket mechanism 7, the movement of the second pin 8 in the second direction is restricted, thereby realizing the connection of the third socket and the fourth socket by the second pin 8, and thus realizing the lateral connection of the first composite plate 1 and the second composite plate 2.

[0052] Furthermore, the bottom of the socket body is fixed to the mounting plate, and the two sides of the mounting plate are fixed to the bottom groove surface of the second groove 4 by bolts.

[0053] The adjacent second socket mechanisms 7 are arranged in opposite directions.

[0054] Furthermore, the top surfaces of the first composite plate 1 and the second composite plate 2 are provided with grouting holes 9, which extend to the corresponding second groove 4, so that the grouting holes 9 are connected to the internal space of the second groove 4.

[0055] Bolts 10 are also provided in the second groove 4. Bolts 10 are embedded in the composite plate and are used to connect the sealing plate 11. When the second groove 4 is grouted, the sealing plate 11 can be used to inject concrete slurry into the second groove 4.

[0056] Example 2 This embodiment provides a construction method for the composite slab pin-type lateral connection structure described in Embodiment 1, including the following steps: Step 1: Hoist the first composite plate 1 and the second composite plate 2 so that the sides of the first composite plate 1 and the second composite plate 2 used for lateral connection fit together, the corresponding first groove 3 forms a first space, and the corresponding second groove 4 forms a second space.

[0057] Step 2: Insert the first pin 6 into the first socket mechanism 5 in the first space, and insert the second pin 8 into the second socket mechanism 7 in the second space.

[0058] Step 3: Attach the sealing plate 11 to the open side of the second groove 4 to seal the second groove 4. The bolt 10 passes through the fixing hole on the sealing plate 11 and the nut 12 is tightened on the bolt so that the nut 12 presses the sealing plate 11 against the lower surface of the first composite plate 1 and the second composite plate 1.

[0059] Step 4: Concrete is poured into the second space formed by the second groove 4 through the grouting holes 9 opened on the upper surface of the first composite plate 1 and the second composite plate 2, and concrete is poured directly into the first space formed by the first groove 3. The poured concrete is flush with the corresponding plate surfaces of the first composite plate 1 and the second composite plate 2.

[0060] Step 5: After the concrete has cured, insert the nut 12 and remove the sealing plate 11 to complete the lateral connection between the first composite plate 1 and the second composite plate 2.

[0061] In this embodiment of the lateral connection structure and construction method, when laterally connecting two laminated plates, the first pin 6 is inserted into the first socket mechanism 5, and the second pin 8 is inserted into the second socket mechanism 7. The lateral connection of the two laminated plates is achieved through the cooperation between the first pin 6, the first socket mechanism 5, the second pin 8, and the second socket mechanism 7. Simultaneously, the first socket mechanism 5 is located within the space formed by the first groove 3, and the second socket mechanism 7 is located within the space formed by the second groove 4. The lateral connection is achieved using the first pin 6, the first socket mechanism 5, the second pin 8, and the second socket mechanism 7. After connection, concrete can be poured into the first groove 3 and the second groove 4 so that the first pin 6, the first socket mechanism 5, the second pin 8 and the second socket mechanism 7 are embedded in the concrete, thus ensuring that the surface of the two composite plates is flat and beautiful after assembly. The two composite plates are laterally connected by the cooperation of the socket mechanism and the pin. During construction, the construction personnel only need to insert the pin in the socket mechanism, without the need for straightening and binding of the steel bars, which greatly reduces the construction time, improves the construction efficiency, and reduces the skill requirements of the construction personnel. The quality of the lateral connection is well controllable.

[0062] Example 3 This embodiment provides a floor slab with the composite plate pin-type lateral connection structure described in Embodiment 1. The remaining structure of the floor slab can be achieved using existing technology and will not be described in detail here.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
